MG
The Classic Marque

Nice, I plan to use my car to bimble around Warwickshire countryside with the gf, but have uprated it to not feel like a target on the motorway, trying so very hard to not turn it into a racer as I know after spending a fortune it will still be slow !

So you need to focus on getting heat away from your fuel lines, your fuel pump and shielding your fuel tank.

Malcolm I have a copy of Daniel Stapleton's book and dip into it from time to time but it is aimed more at the all-out racer. I should probably have looked to see what he says about the issue before posting.

My track activities are limited to a dozen or so club-level hill climbs each year as well as MASC and other social meetings and leisure runs. I am sticking to Interclub Class 1A Roadg...

Colin,

No worries, Malc is often autocorronged to Mark.

If racing my Sprite was my thing, I'd have either a saddle tank for fuel and a dam great big duct coming out of the trans tunnel - or vent it through the 'back seat' area or boot.

I have seen a lot of racing Spridgets with vents in the wings or if running a GRP bonnet, I'd be tempted to vent that.

Have you got a c...

Malcolm (apologies for the Mark last time)

Thank you for that link, it is really helpful. I probably knew most of it already - I just hadn't put the pieces together and thought it through sufficiently.

I've started researching insulation for the pipework and thinking of ways to improve the air flow through the engine bay and transmission tunnel.

Colin,

Worth a read ?

Malc

That's a pretty obvious one that hadn't crossed my small mind!

The pipe runs along the bottom lip of the tunnel after going over the top of the axle before the pump. I'll try insulating it.

Thanks Mark.

Doesn't all the hot air from the engine bay exit via the trans tunnel ?


And where do you run the fuel line - down the trans tunnel or under it ?

S G Kiel,

They look more secure than the ones with a hole in, you have release the speedbleeders and then the bleeder comes of the seat, whereas with yours they stay seated until fluid pressure lifts the seal.

This might be a one-off that will never happen again, but, with global warming, perhaps it will recur.

It was 32 degrees in the shade at Loton Park Hill Climb on Saturday but a good deal more for the Sprite parked in direct sun on the tarmac paddock, albeit with a sp...

Thanks Willy
